Metal Technology has been manufacturing laboratory crucibles out of Zirconium, Molybdenum, Niobium, Tantalum, Titanium, Vanadium, Nickel, and Inconel for over forty years. We are often asked by our customers why our crucibles last longer than other suppliers and the answer to that question comes from how our crucibles are made. We made the decision many years ago to press form our crucibles instead of spinning them because we believe that press formed crucibles provide much better overall quality for the following reasons. Press formed crucibles will typically have a more consistent wall thickness throughout the crucible. Press formed crucibles will be more consistent dimensionally when compared to typical hand spun crucibles. Some hand spun crucibles we have seen have shown localized wall thinning of approximately 50%, meaning that you are really buying a 1mm wall thickness crucible and paying for a 2mm wall thickness crucible. Most hand spun zirconium crucibles are heated while spinning and thus form oxides on the surface, affecting grain size, which could affect the life cycle of the crucible. MTI cold forms their crucibles to assure that the material properties are not impacted. Zirconium is our most effective crucible material for fusions using sodium carbonate or sodium peroxide. It is an excellent low-cost replacement for platinum. And, based on an average of 100 fusions per crucible, it is more cost effective than less expensive porcelain or steel crucibles. The major use of zirconium remains in the nuclear reactor arena. The thermal neutron capture cross-section is extremely low so the metal acts as a window to these particles.
